Hair Follicle Drug Testing - Marlette, MI

What it is, How it works

Hair testing is now widely recognized as an effective means for identifying the use of drugs and alcohol. It offers an extended timeline of usage by capturing biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can reveal substance use for a period of up to 3 months. This method is easy to gather, tough to tamper with, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil in thickness) near the scalp yields 100mg, an optimal amount for both screening and confirmation. For EtG assessments, extra panels, or tests above 10 panels, it's advisable to collect 150mg. We suggest using a jeweler’s scale to measure the specimen. Should scalp hair not be accessible, a similar quantity of body hair can be used. When mentioning head hair, we specifically mean scalp hair, while body hair encompasses all other hair types (e.g., facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test result encompasses four stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab's system. This involves confirming the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and completing any missing data not provided by an electronic chain of custody mechanism.

Screening serves as a preliminary rapid check for drugs of misuse. Though Screening is a cost-efficient method to exclude drug consumption in most samples, a positive screening necessitates confirmation for legal acceptance. Specimens with a presumptive positive in Screening must undergo further confirmation.

When a sample tests presumptively positive during Screening, additional hair is retrieved from the original specimen for Extraction. Here, drugs are extracted at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing a challenging procedure.

Confirmation of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS technology. Presumptive positive samples are cleansed before confirmation, as necessary. The entire lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can reveal substance use up to 90 days, unlike urine tests which offer a shorter detection span.
• Difficult to manipulate: Cheating a hair drug test is very challenging, resulting in more precise outcomes.
• Chronological data provided: This method can map drug use over time, beyond just recent usage.

Limitations:

• Cannot reveal recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to other testing techniques.
• Result variations: Hair color and personal hair growth rates can influence drug metabolite concentrations within the hair.

Note: Although often termed "hair follicle tests", the procedure examines the hair strand rather than the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
